Gaultheria plant named ‘Gaulbri 1’

ABSTRACT

A new cultivar of  Gaultheria procumbens  plant named ‘Gaulbri1’ that is characterized by its foliage that is variegated with green centers and margins that are white to pink in color with some sectional variegation that is white, light green, pink and dark green in color, and its berries that are pink in color when young and turn red in color when they mature.

Botanical classification: Gaultheria procumbens.

Cultivar designation: ‘Gaulbri1’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar ofGaultheria procumbens, known as Gaultheria ‘Gaulbri1’ and is hereinafterreferred to by its cultivar name ‘Gaulbri1’.

‘Gaulbri1’ was found as a natually-occuring variegated branch mutationof an unnamed and unpatented plant of Gaultheria procumbens by theInventor that was growing in a container in a production block at anusery in Elma, Wash. in spring of 2015.

Asexual propagation of the new cultivar was first accomplished by tissueculture using meristemac tissue under the direction of the Inventor inElma, Wash. in July of 2015. Asexual propagation of the new cultivar bytissue culture has shown that the unique features are stable andreproduced true to type in successive generations.

SUMMARY OF THE INVENTION

The following traits have been repeatedly observed and represent thecharacteristics of the new cultivar. These attributes in combinationdistinguish ‘Gaulbri1’ as a new and unique cultivar of Gaultheria.

-   -   1. ‘Gaulbri1’ exhibits foliage that is variegated with green        centers and margins that are white to pink in color with some        sectional variegation that is white, light green, pink and dark        green in color.    -   2. ‘Gaulbri1’ exhibits berries that are pink in color when young        and turn red in color when they mature.

The parent plant of ‘Gaulbri1’ is similar to ‘Gaulbri1’ in flower andberry color, but differs from ‘Gaulbri1’ in having leaves that are soliddark green in color. ‘Gaulbri1’ can be most closely compared toGaultheria procumbens cultivars ‘Gaulsidh11’ (U.S. Plant patentapplication Ser. No. 29,094)* and ‘Gaulsidh5’ (U.S. Plant Pat. No.29,093)*. Both are similar to ‘Gaulbri1’ in plant habit and in havingflowers that are white in color and mature berries that are red incolor. ‘Gaulsidh11’ differs from ‘Gaulbri1’ in having leaves that aresolid dark green in color and a higher berry set. ‘Gaulsidh5’ differsfrom ‘Gaulbri1’ in having larger berries and leaves that are solid greenin color. * Examiner has permission to replace the U.S. Plant PatentApplication Nos. with U.S Plant Patent Nos. and delete this statement.

BRIEF DESCRIPTION OF THE DRAWINGS

The accompanying colored photographs illustrate the overall appearanceand distinct characteristics of the new Gaultheria. The photographs weretaken of a plant 2 years in age as grown in a poly greenhouse in Elma,Wash.
